Description

This lecture introduces the concepts of microstates and macrostates, focusing on the statistical definition of entropy. It covers the ergodic hypothesis, observables as averages, ensemble averages, and the equiprobability axiom. The density of states and its relation to the dimensionality of systems are also discussed, using examples like the (3D) Particle in a Box.
